[0027] See also Figure 2 , Figure 4 , Figure 5 , Figure 6 and Figure 7 An auxiliary block 514 is fixedly connected to the center of the bottom of the inner cavity of the transverse groove 518, and springs 515 are fixedly connected to the left and right sides of the auxiliary block 514. The other end of the spring 515 is fixedly connected to a clamping block 512, and an arc block 513 is fixedly connected to the center of the surface of the clamping block 512;

[0028] See also Figure 2 , Figure 4 , Figure 5 , Figure 6 and Figure 7 The top bolt on the left side of the housing 1 is equipped with a synchronous motor 510, and a screw 507 is fixedly connected to the output end of the synchronous motor 510 and located between the lower fixed plate 502 and the upper auxiliary plate 511. A displacement plate 505 is threadedly sleeved on the surface of the screw 507, and a tooth 504 is provided on the top of the displacement plate 505;

[0029] See also Figure 2 , Figure 4 , Figure 5 , Figure 6 and Figure 7 A rotating rod 508 is installed in the inner cavity of the housing 1 and located between the lower fixed plate 502 and the upper auxiliary plate 511. A cam 509 is installed on the surface of the rotating rod 508 and located at the top of the transverse groove 518. A gear 506 is installed on the surface of the rotating rod 508 and located at the top of the tooth 504.

[0030] See also Figure 3 and Figure 4 The bag filter 4 includes a fixed cylinder 403, and a card slot 402 is provided on both sides of the fixed cylinder 403. A dust bag cylinder 401 is fixedly installed at the bottom of the fixed cylinder 403;

[0031] The upper arc groove 520 is adapted to the cam 509;

[0032] By providing the exhaust port 2 and the detachable cover 3, the detachable cover 3 can cover the top of the housing 1, and the exhaust port 2 guides the filtered gas to be discharged. By providing the card slot 402 and the card block 512, the positioning card assembly can be performed. When the card block 512 is inserted, the fixed cylinder 403 is prevented from moving up and down at will and separating from the upper auxiliary plate 511.

[0033] By setting the fixed cylinder 403, it can be installed through the empty slot 501 on the upper auxiliary plate 511, and its shape design can prevent the fixed cylinder 403 from completely moving down and sinking into the empty slot 501. By setting the empty slot 501, the space requirement for the dust bag cylinder 401 to pass through and the space requirement for the installation of the fixed cylinder 403 can be met;

[0034] By providing the auxiliary groove 503, it can be adapted to the rotating rod 508 to meet the installation space requirement of the rotating rod 508. By providing the teeth 504 and the gears 506, it can play the role of meshing transmission. When the displacement plate 505 generates a lateral displacement, the multiple gears 506 rotate synchronously.

[0035] By setting the screw rod 507 and the displacement plate 505, a screw transmission function can be achieved. The displacement plate 505 can be laterally displaced under the drive of the synchronous motor 510. By setting the rotating rod 508, the fixed installation requirements of multiple cams 509 and screw rods 507 can be met, so that the cams 509, the screw rods 507 and the rotating rods 508 can rotate synchronously.

[0036] By setting the arc block 513, it can be adapted to the cam 509. When the cam 509 rotates, it drives the clamping block 512 to move left and right. By setting the auxiliary block 514, the fixed installation requirements of the two springs 515 can be met at the same time, and the staggered design with the lower arc groove 517 can avoid the auxiliary block 514 from blocking the rotation of the cam 509.

[0037] When in use, all components are in the initial installation state, spring 515 is in a stretched state, and the smoke-containing gas is introduced into the shell 1 through the air inlet 6. Under the filtering action of the dust bag tube 401, larger dust impurities fall and are collected and discharged by the ash hopper 7, while smaller dust impurities are intercepted and processed by the dust bag tube 401. After long-term use, the dust bag tube 401 needs to be replaced. First, the synchronous motor 510 is controlled to work in the forward direction to drive the screw 507 to rotate. Under the thread transmission, the displacement plate 505 is displaced to the left. Under the meshing transmission of the teeth 504 and the gear 506, multiple rotating rods 508 are rotated at the same time, and the cam 509 rotates clockwise, that is, the right end of the cam 509 rotates downward and enters the lower arc groove 517, and the left end of the cam 509 rotates upward and enters the upper arc groove 520. As the cam 509 rotates, its left end enters the upper arc groove 520 and then engages with the flat groove 521. The upper and lower magnetic blocks 522 are no longer in magnetic contact, so as to drive the fixed cylinder 403 to move up synchronously. At the same time, when the cam 509 rotates from the horizontal state to the vertical state, the block 512 is automatically reset inwardly under the elastic connection of the spring 515, and the block 512 no longer cooperates with the card slot 402 to clamp the fixed cylinder 403, which can meet the normal up and down displacement requirements of the fixed cylinder 403. The staff can move the fixed cylinder 403 up and take it out, driving the dust bag cylinder 401 to move up synchronously. At this time, the synchronous motor 510 is controlled to work in reverse, and the cam 509 is turned from the vertical state to the horizontal state. With the assistance of the arc block 513, the block 512 is again extended and placed in the empty slot 501. When the dust bag cylinder 401 moves up, the block 512 can assist in scraping the dust bag cylinder 401, thereby greatly reducing the subsequent cleaning intensity of the dust bag cylinder 401.

[0038] In summary: the bag-type dust collector for waste gas filtration and smoke recovery in crude lead production solves the problem that the basic bag-type dust collector cannot conveniently lift and remove multiple bags, and does not have the function of auxiliary dust removal during the removal process, and needs to perform large-area cleaning operations on the bags, increasing the subsequent cleaning intensity, and has certain limitations by providing bag-type filter elements 4 and convenient expansion and support mechanisms 5.
